無法循環使用PHP的XML Soap文件中的兒童

Question

我一直在這個問題上擱置了很長時間，並希望有人可以提供幫助。這是我第一次通過Xpath方法解析SOAP。我有一個來自Bing的地理位置數據集，我試圖遍歷並寫入MYSQL表。我公司通過遍歷XML文件看起來是這樣的：

<?xml version="1.0" encoding="utf-8"?> 
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> 
    <s:Header /> 
    <s:Body>

     </a:Countries> 
     </GetGeographicalLocationsResult> 
    </GetGeographicalLocationsResponse> 
    </s:Body> 
</s:Envelope> 

我的PHP代碼如下所示：

$file = 'soap-example-2.xml'; 
$xml = simplexml_load_file($file, NULL, NULL, "http://schemas.xmlsoap.org/soap/envelope/"); 
$xml->registerXPathNamespace('s', 'http://schemas.xmlsoap.org/soap/envelope/'); 
$xml->registerXPathNamespace('a', 'http://schemas.datacontract.org/2004/07/Microsoft.BingAds.Advertiser.CampaignManagement.MT.Messages'); 
$xml->registerXPathNamespace('i', 'http://www.w3.org/2001/XMLSchema-instance'); 
$xml->registerXPathNamespace('b', 'http://schemas.datacontract.org/2004/07/Microsoft.BingAds.Advertiser.CampaignManagement.MT.Entities'); 

$num_rows = count($xml->xpath('//b:Country/b:SubGeographyAreas/b:SubGeography/b:MetroAreas/b:MetroArea/b:Cities/b:City')); 
echo $num_rows; 

foreach($xml->xpath('//b:Country/b:SubGeographyAreas/b:SubGeography/b:MetroAreas/b:MetroArea/b:Cities/b:City') as $city) 
{ 
    for ($i=0; $i < $num_rows; $i++) { 
     echo $city->Name[$i]; 
    } 
} 

我無法通過城市節點loopiong呼應出城的所有孩子。在我上面的php中，我只是試圖回顯每個城市名稱。如果它正常工作，將呼應了這一點：

任何幫助將不勝感激！我確信這是一個簡單的事情，我忽略了。

我看不到內部for循環的目的。每個城市只有一個Name，對吧？您是否嘗試過這樣的：

$bNs = 'http://schemas.datacontract.org/2004/07/Microsoft.BingAds.Advertiser.CampaignManagement.MT.Entities'; 
$cityPath = '//b:Country/b:SubGeographyAreas/b:SubGeography/b:MetroAreas/b:MetroArea/b:Cities/b:City'; 
foreach($xml->xpath($cityPath) as $city) 
{ 
    echo $city->children($bNs)->Name; 
}
